THE WORLD'S COTTONS — HUTCHINSON 515 



Following Gerstel's suggestion and the carcheological indications re- 

 ported by Engel, it is possible to set out the conditions governing the 

 possibility of a transatlantic link, and to point to two lines of investi- 

 gation — archeological in Peru and botanical east of the Andes — that 

 might make it possible to decide between the two hypotheses. This is 

 a new and unexpected turn in the inquiry into the origin of the cottons. 

 No mention has been made here of the third allopolyploid, G. tomen- 

 tosum^ which is a wild fuzzy-seeded — but not linted — species in 

 Hawaii. Ever since the cytological situation in the genus was set out 

 it has seemed that if the origin and relationship of G. tomentosum 

 could be elucidated, the problem of the New World cottons would be 

 solved. Now it appears that the origin of G. tomentosum is a separate 

 and probably unimportant problem, and the real interest lies in the 

 Peruvian Andes, and in the origin of the earliest cotton farmers of the 

 Peruvian coast.
